“…While the study serves as a first step towards assessment of system performance and robustness, there is scope for further work. There are other criteria for vulnerability that may provide valuable insights, such as resilience (adaptability, persistence, transformability), and other locally defined categories [60]. Furthermore, this study focused on the CMIP5 GCMs, while Regional Climate Models (RCMs) or other models may enrich the analysis.…”

“…Performance and vulnerability of the system is primarily evaluated using reliability as a key metric, along with flow duration characteristics, environmental shortage and robustness. These metrics are a selection of a wide range of water security evaluation criteria used in decision-scaling approaches [60]. Although in-depth assessment of environmental flow requirements is lacking in the IBB, several assessments suggest a minimum annual inflow to the Ili delta of 11 BCM to maintain the wetlands and Lake Balkhash [9,24,61,62].…”

The Ili-Balkhash basin (IBB) is considered a key region for agricultural development and international transport as part of China’s Belt and Road Initiative (BRI). The IBB is exemplary for the combined challenge of climate change and shifts in water supply and demand in transboundary Central Asian closed basins. To quantify future vulnerability of the IBB to these changes, we employ a scenario-neutral bottom-up approach with a coupled hydrological-water resource modelling set-up on the RiverWare modelling platform. This study focuses on reliability of environmental flows under historical hydro-climatic variability, future hydro-climatic change and upstream water demand development. The results suggest that the IBB is historically vulnerable to environmental shortages, and any increase in water consumption will increase frequency and intensity of shortages. Increases in precipitation and temperature improve reliability of flows downstream, along with water demand reductions upstream and downstream. Of the demand scenarios assessed, extensive water saving is most robust to climate change. However, the results emphasize the competition for water resources among up- and downstream users and between sectors in the lower Ili, underlining the importance of transboundary water management to mitigate cross-border impacts. The modelling tool and outcomes may aid decision-making under the uncertain future in the basin.

“…Tanner [6] et al evaluated water resource resilience from the perspective of social policy, but the indicators were not quantitative and did not consider the resilience of urban ecological environment system. Simonovic [7] and Jim [8] et al studied the water toughness and evaluated the water toughness with a mathematical model. Based on layer theory, Kong [9] et al used network analysis method to dynamically evaluate the interdependent toughness of urban water supply network, communication network and power network.…”

Under the influence of global climate change, urban flood and drought disasters occur frequently, so that is extremely important to construct the resilience capacity of urban water supply system. Based on the framework of system toughness and capability analysis, using correlation analysis and factor analysis to construct the index system of resilience capacity assessment of urban water supply system, which reflects the four dimensions of water source, water plants, water supply and distribution network and users, and five dimensions of social, natural environment, economy, physics and organization, and the weights of all indexes are given. The multi-level comprehensive evaluation model based on cloud model and the index comprehensive evaluation index method based on entropy weight were used to evaluate the resilience of the water supply system in Qingdao under flood and drought disasters, and the evaluation results of the two methods were compared. Finally, based on the evaluation results, the influencing factors of water supply system resilience were analyzed, and the corresponding strategies to improve the resilience of water supply system were proposed, in order to provide decision support for the planning and construction of urban water supply system resilience in the near and long term.

Ensemble members from weather and climate predictions can be used to generate large samples of simulated weather events, allowing the estimation of extreme (hitherto unseen) events. Here, we provide a protocol and open workflow for applying the ‘UNSEEN’ method for hydro-climatic extremes globally, based on Copernicus Climate Change Services (C3S) seasonal predictions but also considering other compatible modelling systems. We discuss common challenges and potential solutions using three examples of extreme events that caused severe damage in 2020 (extreme rainfall, heat, and wildfire danger). These case studies demonstrate the potential of the method to inform decision-making with maximum credible events used for stress-testing adaptation measures and to anticipate unprecedented extremes in a changing climate. As such, this paper may be used to guide the generation of large ensembles that are a credible resource for evaluating otherwise unforeseen hydro-climatic risks.
